The
dress was worn by the bride's mother. McNeill and her friends
first realized something was different about the dress when the
mother sent her daughter the now-famous photo.

"What happened was two of my close friends were actually getting
married and the mother of the bride took a photo of the dress to
send to her daughter," McNeill said. "When my friend showed the
dress to her fiancé, they disagreed on the color."

The bride then posted the picture on Facebook, and her friends
continued to debate the color of the dress.

"All of our friends disagreed," McNeill said.

After seeing the Facebook thread, McNeill decided to share the
picture on a fan page she has on Tumblr dedicated to a woman
named Sarah Weichel. That was where the dress went viral.

Weichel is a talent manager who represents several YouTubers
including Hannah Hart.

Weichel told Business Insider her phone began blowing up on
Thursday after McNeill's post started going viral.

"The crazy thing is, I actually have nothing to do with the
post," Weichel said. "It's literally just a fan account of me, so
my name and my photos are all over the account. I actually don't
have anything to do with it ... But I have been getting a ton of
phone calls and emails tonight."

"Between that announcement and the dress thing my phone has been
going crazy with congratulations and, 'What the hell is
happening?'" Weichel said.

For Weichel, there is no question about what color the dress
is.

"Black and blue of course!" she said.

Weichel put Business Insider in touch with McNeill, who said one
of the oddest parts of the experience had been watching
celebrities share her picture.

"I thought my followers on Tumblr would maybe have a good
reaction, but I never would have considered that Taylor Swift and
Mindy Kaling would be tweeting about it," McNeill said.

Of all the celebrities who became interested in her post, McNeill
would like to meet Swift.

"Oh my god," she said when we asked about Swift. "That would be
something."

McNeill plays
guitar and sings in a band named Canach that plays what she
described as "traditional Scottish folky music." Her band played
at the wedding. She actually saw the dress in person and told us
definitively what color it really was.

"I got to the wedding and the mother was wearing the dress,"
McNeill said. "Obviously it was blue and black."
